Bus Blaster V3c for MIPS Kit

Description of product


Bus Blaster V3c for MIPS is an economical, yet high-speed debug adapter designed for supporting JTAG debug with various MIPS processors. This version of the Bus Blaster has a 14-pin target connector and interface cable with buffering logic suitable for MIPS EJTAG targets. In other respects it is the same as the standard Bus Blaster V3c

For MIPS hardware and software debugging, Bus Blaster is recommended to be used with OpenOCD JTAG programming and debugging software which can be downloaded from SourceForge.

For software development, compiling, building programs, and source debugging with GDB, the Codescape MIPS SDK Essentials is a free download available from the Imagination Technologies website. Download Codescape SDK Essentials here.

Bus Blaster can be used with various other debugging, programming and boundary scan test software, so there are a rich variety of resources available for your MIPS development project.
